After the simulations, the private investigator reported to them. "Based on our reenactments, it appears that what the gangster said in his statement was accurate. His motion path on stage was the best possible one—hiding behind the curtains backstage, under the drum set, moving rapidly when the lights went out. The person that designed the path of movement must have surveyed the venue many times."
Xia Ling and Li Lei exchanged a glance.
Li Lei instructed. "Find out who came into the venue before the concert, as well as where Young Master Wang, the murderer, and Xia Yu went in the three months before the incident."
The private investigator went off to do his bidding.
